The links without transformation into a latin symbol is poorly ranking in the search results.
Wikipedia:
A slug is the part of a URL which identifies a page using human-readable keywords.
To make the URL easier for users to type, special characters are often removed or replaced as well. For instance, accented characters are usually replaced by letters from the English alphabet; punctuation marks are generally removed; and spaces (which have to be encoded as %20 or +) are replaced by dashes (-) or underscores (_), which are more aesthetically pleasing.
For example user: @ригнпирои have this link
